For any surface of other lenses in the optical image capturing system, the ratio between the profile curve length of the maximum effective half diameter thereof and the thickness of the lens which the surface belonged to is denoted in the same manner.

For any surface of any lens, the profile curve length within a half of the entrance pupil diameter (HEP) affects the ability of the surface to correct aberration and differences between optical paths of light in different fields of view. With longer profile curve length, the ability of correcting aberration is better. However, the difficulty of manufacturing increases as well.

Herein the weak refractive power means the absolute value of the focal length of one specific lens is greater than 10. When at least one lens among the second to the fourth lenses has weak positive refractive power, it may share the positive refractive power of the first lens, and on the contrary, when at least one lens among the second to the fourth lenses has weak negative refractive power, it may finely correct the aberration of the system.

In an embodiment, the fifth lens could have negative refractive power, and an image-side surface thereof is concave, it may reduce back focal length and size. Besides, the fifth lens can have at least an inflection point on at least a surface thereof, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The number of aspheric glass lenses could be less than the conventional spherical glass lenses that is helpful for reduction of the height of the system.

Second Embodiment

As shown in FIG. 2A and FIG. 2B, an optical image capturing system 20 of the second embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture 200, a first lens 210, a second lens 220, a third lens 230, a fourth lens 240, a fifth lens 250, an infrared rays filter 280, an image plane 290, and an image sensor 292. FIG. 2C is a transverse aberration diagram at 0.7 field of view of the second embodiment of the present application.

The first lens 210 has positive refractive power, and is made of plastic. An object-side surface 212 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 214 thereof, which faces the image side, is a concave aspheric surface. The image-side surface 214 has an inflection point thereon.

The second lens 220 has negative refractive power, and is made of plastic. An object-side surface 222 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 224 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 222 has an inflection point thereon.

The third lens 230 has positive refractive power, and is made of plastic. An object-side surface 232, which faces the object side, is a convex aspheric surface, and an image-side surface 234, which faces the image side, is a concave aspheric surface. The image-side surface 234 has an inflection point.

The fourth lens 240 has positive refractive power, and is made of plastic. An object-side surface 242, which faces the object side, is a convex aspheric surface, and an image-side surface 244, which faces the image side, is a convex aspheric surface. The object-side surface 242 and the image-side surface 244 both have an inflection point.

The fifth lens 250 has negative refractive power, and is made of plastic. An object-side surface 252, which faces the object side, is a concave surface, and an image-side surface 254, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 252 and the image-side surface 254 both have an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 280 is made of glass, and between the fifth lens 250 and the image plane 290. The infrared rays filter 280 gives no contribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies |f2|+|f3|+|f4|=30.2470 mm; |f1|+|f5|=10.0680 mm; and |f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens 220, f3 is a focal length of the third lens 230, f4 is a focal length of the fourth lens 240, and f5 is a focal length of the fifth lens 250.

In the second embodiment, the first lens 210, the third lens 230, and the fourth lens 240 are positive lenses, and their focal lengths are f1, f3, and f4. The optical image capturing system of the second embodiment further satisfies ΣPP=f1+f3+f4=23.85400 mm; and f1/(f1+f4+f5)=0.27115, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens 210 to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the second embodiment further satisfies ΣNP=f2+f5=−16.46100 mm; and f5/(f2+f5)=0.21870, where f2 is a focal length of the second lens 220, f5 is a focal length of the fifth lens 250, and ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the fifth lens 250 to the other negative lens.

Third Embodiment

As shown in FIG. 3A and FIG. 3B, an optical image capturing system of the third embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture 300, a first lens 310, a second lens 320, a third lens 330, a fourth lens 340, a fifth lens 350, an infrared rays filter 380, an image plane 390, and an image sensor 392. FIG. 3C is a transverse aberration diagram at 0.7 field of view of the third embodiment of the present application.

The first lens 310 has positive refractive power, and is made of plastic. An object-side surface 312 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 314 thereof, which faces the image side, is a concave aspheric surface.

The second lens 320 has negative refractive power, and is made of plastic. An object-side surface 322 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 324 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 322 has an inflection point thereon, and the image-side surface 324 has two inflection points.

The third lens 330 has positive refractive power, and is made of plastic. An object-side surface 332 thereof, which faces the object side, is a convex surface, and an image-side surface 334 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 332 has two inflection points, and the image-side surface 334 has an inflection point.

The fourth lens 340 has positive refractive power, and is made of plastic. An object-side surface 342, which faces the object side, is a concave aspheric surface, and an image-side surface 344, which faces the image side, is a convex aspheric surface. The object-side surface 342 and the image-side surface 344 both have an inflection point.

The fifth lens 350 has negative refractive power, and is made of plastic. An object-side surface 352, which faces the object side, is a convex surface, and an image-side surface 354, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 352 and the image-side surface 354 both have an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 380 is made of glass, and between the fifth lens 350 and the image plane 390. The infrared rays filter 390 gives no contribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies |f2|+|f3|+|f4|=66.4260 mm; |f1|+|f5|=8.4060 mm; and |f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens 320, f3 is a focal length of the third lens 330, f4 is a focal length of the fourth lens 340, and f5 is a focal length of the fifth lens 350.

In the third embodiment, the first lens 310, the third lens 330, and the fourth lenses 340 are positive lenses, and their focal lengths are f1, f3, and f4. The optical image capturing system of the third embodiment further satisfies ΣPP=f1+f3+f4=27.25000 mm; and f1/(f1+f3+f4)=0.23927, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens 310 to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the third embodiment further satisfies ΣNP=f245=−47.58200 mm; and f5/(f2+f5)=0.03964, where f2 is a focal length of the second lens 320, f5 is a focal length of the fifth lens 350, and ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the fifth lens 350 to the other negative lens.

Fourth Embodiment

As shown in FIG. 4A and FIG. 4B, an optical image capturing system 40 of the fourth embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture 400, a first lens 410, a second lens 420, a third lens 430, a fourth lens 440, a fifth lens 450, an infrared rays filter 480, an image plane 490, and an image sensor 492. FIG. 4C is a transverse aberration diagram at 0.7 field of view of the fourth embodiment of the present application.

The first lens 410 has positive refractive power, and is made of plastic. An object-side surface 412 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 414 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 412 and the image-side surface 414 both have an inflection point.

The second lens 420 has negative refractive power, and is made of plastic. An object-side surface 422 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 424 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 422 and the image-side surface 424 respectively have an inflection point.

The third lens 430 has positive refractive power, and is made of plastic. An object-side surface 432 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 434 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 432 and the image-side surface 434 both have an inflection point.

The fourth lens 440 has positive refractive power, and is made of plastic. An object-side surface 442, which faces the object side, is a concave aspheric surface, and an image-side surface 444, which faces the image side, is a convex aspheric surface. The image-side surface 444 has two inflection points.

The fifth lens 450 has negative refractive power, and is made of plastic. An object-side surface 452, which faces the object side, is a convex surface, and an image-side surface 454, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 452 and the image-side surface 454 both have an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 480 is made of glass, and between the fifth lens 450 and the image plane 490. The infrared rays filter 480 gives no contribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies |f2|+|f3|+|f4|=19.5740 mm; |f1|+|f5|=13.3330 mm; and |f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens 420, f3 is a focal length of the third lens 430, f4 is a focal length of the fourth lens 440, and f5 is a focal length of the fifth lens 450.

In the fourth embodiment, the first lens 410, the third lens 430, and the fourth lenses 440 are positive lenses, and their focal lengths are f1, f3, and f4. The optical image capturing system of the fourth embodiment further satisfies ΣPP=f1+f3+f4=20.31800 mm and f1/(f1+f3+f4)=0.29772, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens 410 to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the fourth embodiment further satisfies ΣNP=f245=−12.58900 mm, and f5/(f2+f5)=0.57860, where f2 is a focal length of the second lens 420, f5 is a focal length of the fifth lens 450, and ΣNP is a sum of the focal lengths of each negative lens.

Fifth Embodiment

As shown in FIG. 5A and FIG. 5B, an optical image capturing system of the fifth embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture 500, a first lens 510, a second lens 520, a third lens 530, a fourth lens 540, a fifth lens 550, an infrared rays filter 580, an image plane 590, and an image sensor 592. FIG. 5C is a transverse aberration diagram at 0.7 field of view of the fifth embodiment of the present application.

The first lens 510 has positive refractive power, and is made of plastic. An object-side surface 512, which faces the object side, is a convex aspheric surface, and an image-side surface 514, which faces the image side, is a concave aspheric surface. The image-side surface 514 has an inflection point thereon.

The second lens 520 has negative refractive power, and is made of plastic. An object-side surface 522 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 524 thereof, which faces the image side, is a convex aspheric surface.

The third lens 530 has positive refractive power, and is made of plastic. An object-side surface 532, which faces the object side, is a concave aspheric surface, and an image-side surface 534, which faces the image side, is a convex aspheric surface. The image-side surface 534 has two inflection points thereon.

The fourth lens 540 has positive refractive power, and is made of plastic. An object-side surface 542, which faces the object side, is a concave aspheric surface, and an image-side surface 544, which faces the image side, is a convex aspheric surface. The object-side surface 542 and the image-side surface 544 both have two inflection points.

The fifth lens 550 has negative refractive power, and is made of plastic. An object-side surface 552, which faces the object side, is a convex surface, and an image-side surface 554, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 552 and the image-side surface 554 both have an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 580 is made of glass, and between the fifth lens 550 and the image plane 590. The infrared rays filter 580 gives no contribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies |f2|+|f3|+|f4|=86.0870 mm; |f1|+|f5|=7.1540 mm; and |f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens 520, f3 is a focal length of the third lens 530, f4 is a focal length of the fourth lens 540, and f5 is a focal length of the fifth lens 550.

In the fifth embodiment, the first lens 510, the third lens 530, and the fourth lenses 540 are positive lenses, and their focal lengths are f1, f3, and f4. The optical image capturing system of the fifth embodiment further satisfies PP=f1+f3+f4=54.61300 mm; and f1/(f1+f3+f4)=0.08787, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens 510 to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the fifth embodiment further satisfies ΣNP=f245=−38.62800, and f5/(f2+f5)=0.06097, where f2 is a focal length of the second lens 520, f5 is a focal length of the fifth lens 550, and ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the fifth lens 550 to the other negative lens.

The parameters of the lenses of the fifth embodiment are listed in Table 9 and Table 10.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system of the sixth embodiment of the present invention includes, along an optical axis from an object side to an image side, an aperture 600, a first lens 610, a second lens 620, a third lens 630, a fourth lens 640, a fifth lens 650, an infrared rays filter 680, an image plane 690, and an image sensor 692. FIG. 6C is a transverse aberration diagram at 0.7 field of view of the sixth embodiment of the present application.

The first lens 610 has positive refractive power, and is made of plastic. An object-side surface 612, which faces the object side, is a convex aspheric surface, and an image-side surface 614, which faces the image side, is a concave aspheric surface. The object-side surface 612 and the image-side surface 614 both have an inflection point.

The second lens 620 has negative refractive power, and is made of plastic. An object-side surface 622 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 624 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 622 and the image-side surface 624 respectively have an inflection point.

The third lens 630 has positive refractive power, and is made of plastic. An object-side surface 632, which faces the object side, is a convex aspheric surface, and an image-side surface 634, which faces the image side, is a convex aspheric surface. The object-side surface 632 has an inflection point.

The fourth lens 640 has positive refractive power, and is made of plastic. An object-side surface 642, which faces the object side, is a concave aspheric surface, and an image-side surface 644, which faces the image side, is a convex aspheric surface. The object-side surface 642 and the image-side surface 644 both have an inflection point.

The fifth lens 650 has negative refractive power, and is made of plastic. An object-side surface 652, which faces the object side, is a convex surface, and an image-side surface 654, which faces the image side, is a concave surface. The object-side surface 652 and the image-side surface 654 both have an inflection point. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 680 is made of glass, and between the fifth lens 650 and the image plane 690. The infrared rays filter 680 gives no contribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies |f2|+|f3|+|f4|=26.1024 mm; |f1|+|f5|=10.9792 mm; and |f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens 620, f3 is a focal length of the third lens 630, f4 is a focal length of the fourth lens 640, and f5 is a focal length of the fifth lens 650.

In the sixth embodiment, the first lens 610, the third lens 630, and the fourth lenses 640 are positive lenses, and their focal lengths are f1, f3, and f4. The optical image capturing system of the sixth embodiment further satisfies ΣPP=f1+244=21.25779 mm; and f1/(f1+f3+f4)=0.35286, where f1 is a focal length of the first lens 610, f3 is a focal length of the third lens 630, f4 is a focal length of the fourth lens 640, and ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of the first lens 610 to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the sixth embodiment further satisfies ΣNP=f2+f5=−15.82380 mm; and f5/(f2+f5)=0.21980, where f2 is a focal length of the second lens 620, f5 is a focal length of the fifth lens 650, and ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the fifth lens 650 to the other negative lens to avoid the significant aberration caused by the incident rays.
